Hi, In the recent days, someone in France imported tens of thousand survey points from the national mapping agency IGN (explicitely permitted). The problem is that many points exists physically at the same lat/lon but different height (e.g on a building, the point has to be visible for different points of views). The points have different descriptions, different references and different altitudes (in the tag 'ele'). But now they are reported as "duplicate nodes" on Matt's map: http://matt.dev.openstreetmap.org/dupe_nodes/?zoom=6&lat=47.16277&lon=1.74968&layers=BT
So would be the best solution to fix this issue ? I see different options: - do nothing (with the risk that a bot will fix it incorrectly in the future) - remove arbitrarily one of the survey points but we loose some information - merge the points into one node and merge the tags using a separator (sounds ugly) - consider multiple nodes with different 'ele' as non-duplicate (and subsequently ask Matt's script to check it). Maybe they are other options. Any advise on this ? Pieren
